Well, posttrans is run at the end of the transaction, so if some
other package fails and the transaction is aborted it'll never
be run. Our gnome folks use it for the same purpose.

I don't really like this solution for the reason stated above,
plus it'll also break prereq semantics. I.e. if a package prereqs
your package, it won't work as the posttrans script isn't run
before the other package gets installed.

But it's currently the only sane way to achieve this (one other
method is a uninstall trigger on the old package).

I hope this will be fixed in the future by some other scriplet
type ("update scripts"). My idea is that if an update script is
present the uninstall scripts are not called, thus you do no
longer have to work around broken uninstall scripts.

Cheers,
  Michael.
